Correlated

Correlated legacy pairs are akin to Curve's Stableswap pools which provide low slippage for traders. The swap curve is:

$$xy(x^2 + y^2) >= k$$

The balance of TokenA and TokenB in the pool will vary based on the current place on the price curve. The closer each asset is to each other in pricing, the closer to 50/50 the pool will be.
